Qingflow

Security checks for vulnerabilities and agentic risk

Overview

The Qingflow workflow includes approval safeguards, but fallback installation can execute unverified code and introduce broader agent changes.

Review and install a verified CLI release yourself before using this skill, and check its automatic skill synchronization settings. Connecting Qingflow allows OOMOL to process your authorized business data. Keep the skill's confirmation requirements for record and workflow changes. No malicious behavior was established, but the fallback installation is insufficiently bounded.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
92% confidence
Finding

The supplied chunk performs remote installer execution rather than Qingflow data operations. Although installation can be a supporting implementation detail, this chunk provides no evidence that the Oomol installer supports the declared Qingflow functionality. The downloaded script's contents and any additional behavior are not available for assessment.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

The installation command streams a remotely hosted, unpinned script directly into Bash without integrity verification or review; the PowerShell alternative uses the same unsafe execution pattern. If the hosting service or distribution pipeline is compromised, attacker-controlled code can execute with the agent process's privileges and potentially access local data and credentials. Restricting installation to a missing-CLI error reduces exposure but does not establish the downloaded code's trustworthiness.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
